#6906: Re-order options for testsrc family of filters in manual -------------------------------------+------------------------------------- Reporter: Misaki | Owner: Type: defect | Status: open Priority: minor | Component: Version: unspecified | documentation Keywords: testsrc | Resolution: Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Changes (by llogan):
* keywords: => testsrc * status: new => open * component: undetermined => documentation Comment: Don't rely on shorthand: it can be ambiguous or confusing and lead to mistakes, and there may be no guarantee that the order will always remain the same. Include the option names with your values: `color=c=white:s=160x160:r=1:d=10:sar=1`. The manual entry is an unorganized combination for the color and other related testsrc based source filters, so trying to count the position of each supported option (and excluding the options specific to the other filters) is not recommended. If you must use shortcuts then refer to `ffmpeg -h filter=color` instead. As you can see from this output `sar` is currently option five. To address this the order in the manual can be changed to: level, c, s, r, d, sar, alpha, n. I did not check the order of other non-testsrc filters. To check them all is arguably a "wontfix" ticket out of pure laziness because reviewing each filter is going to be a boring, mindless job as there are at least 350 filters I estimate, and filter authors may not sync the option order in future filters. Patch welcome! Your output is one frame because you told it to make a frame rate of 1 and a duration of 1 second. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6906#comment:3> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
